How do you represent a coordinate-independent tensor? Don't you still need a basis?
- antognini 8y agoYou just call it something like T. If you want any numbers you need a coordinate basis. For those interested, the first chapter of Kip Thorne's book has a good, though idiosyncratic, explanation of tensors: http://www.pmaweb.caltech.edu/Courses/ph136/yr2012/1201.1.K.pdf http://www.pmaweb.caltech.edu/Courses/ph136/yr2012/1201.1.K....
